Blast Furnace Coke Gas and Converter Gas for Power Production

Blast Furnace Gas. Blast furnace gas is a by-product of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas has a very low heating value of around 0.9kWh/Nm 3 which on its own is typically not high enough for combustion in a gas engine. There is the possibility to blend this gas with other off gases and you should contact your local Clarke Energy office to discuss in more depth.
